That would be tax fraud.
But how bout this. Go get $500 face value legal tender collectable or precious metal containing coins. Give the $500 to whoever you want. Kindly suggest they may want to sell the coins rather than spending them.
Now let’s see the IRS argue that you were not allowed to SPEND your legal tender coins at face value!
Of course, whoever you gave the coins to might get stuck with capital gains if they do not handle disposal of the coins correctly.
